机动车尾气作为环境污染源,是土壤化学污染的一个重要来源。随着我国运输业的发展,机动车拥有量迅速增加,致使公路边重金属污染日趋严重。研究了合肥市长丰县206国道卧龙山段公路旁土壤重金属铅污染状况。结果表明：铅含量随着离路基距离的增加而减少,除山林为轻度污染外,住宅和农田100 m以内为中度污染;铅含量基本随土层深度的增加而减少。

Automobile exhaust,as a source of environmental pollution,is an important source of chemical pollution of soil.Along with the development of transportation,the number of motor vehicles increased rapidly,resulting in heavy metal pollution in roadside growing.Heavy metal（Pb）pollution was studied near Wolong Hill of 206 Highway in Changfeng County.The results showed that：the lead content reduced when the distance from the roadbed increased,in addition to the mountains as light pollution,residential and agricultural land within 100 m as moderate pollution;the lead content reduced when the soil depth increased.
